I know that's a vague question considering that one man's trash is another's treasure, but I'm trying to decide how far down the rabbit hole I want to go. It's an '88 E10RCCD that I acquired on a project boat. When I first fired it up there was no tail tell so I replaced the impeller. Solved that issue. Mounted it on a drift boat and took it for a spin. It started easily, idled find and ran smoothly and smoke free but just wouldn't rev up as I thought it should. Compression check answered that question. I hoped for stuck rings so saturated the cylinders with penetrating and fogging oil for days.
Fired it up and it just screams. Dosed it with fuel system cleaner and screwed that up. It starts fine but only idles on half choke. I likely kicked something lose and plugged a jet, so a carb rebuild will be in order.
Main issue now is that the exhaust seems to be exiting through the small holes above the cavitation plate and not the prop (circled in blue). Additionally the area where the lower unit attaches blackens with oil after running hard in the tank (circled in green). I did replace the two seals on the drive shaft, but am wondering if there's more that I missed. Also I have water ejecting from the small port just below the motor (circled in red).
I've scoured the internet trying to find what would be normal but find nothing very definitive.
Another issue I find interesting is that the motor never seems to warm up. Even after running for an extended period you can touch the cylinder heads comfortably. I pulled the thermostat and it came out surprisingly clean and water flows freely when I BRIEFLY started the motor with the thermostat cover removed.
Would like to hear any thoughts, opinions or advice you guys might have to offer. Thanks in advance.
